设计简介

摘要

为了完成本课题的设计，在设计之前的准备工作必须做好，首先是搜集和分析资料，包括国内外数控机床的发展现状及趋势；初步确定尾座的总体布局，包括配置形式、液压系统的布置及选择与相应的配套元件等，最后主要是关于尾座的设计。
车床设计的主要内容是尾座体、套筒、顶尖、尾座孔系、尾座导四号锥度的尾座顶尖，是利用莫氏锥度自身的结构特性来卡紧尾座顶尖的，它解决了顶尖在工作时会出现松动或转动现象。在套筒中设计了滑键槽和顶尖顶出孔，解决了顶尖在工作时会随套筒转动从而影响工件的加工精度；还在套筒中设计了顶卸的装置，便于顶尖的拆卸。
最后还对尾座体进行机械加工工艺方面的设计，确定合理的加工工艺方案和方法。

Abstract

In order to accomplish the task of design, in the design of the preparation before the work must be done, first is to collect and analyze the data, including domestic and international current situation and development trend of numerical control machine tool tailstock; initially determined the overall layout, including configuration, hydraulic system arrangement and selection and corresponding components, mainly on the tail end block design.
Lathe design are the main contents of the tailstock body, sleeve, top, tailstock hole of tailstock, guide four taper of tailstock center, is the use of Morse taper their structural properties to clamp the tailstock top, which solves the problem of the top in the job will appear when loosening or rotation phenomenon. In the sleeve design of slide key groove and the top top hole, resolved the top when working with the sleeve to rotate so as to influence the machining precision of the workpiece; still sleeve design top unloading device for removing, top.
At the end of the tailstock body mechanical processing technology in the design, determine the reasonable processing scheme and method.
Key Words: Lathe tailstock, design, tailstock, process design
